If one tries to use such an alias as a type declaration the following error would be raised: Fatal error: Cannot use 'int' as class name as it is reserved

Kind of useless as all the above tests already Compile or ParseError.

I added this because if I didn't add the early return in the C code when the use statement is created, it would create a non catchable fatal error.
But yes it is redundant :)

Well, the error message may be helpful, so it's an improvement. I wonder whether we should match the wording with https://3v4l.org/bl5dY; I do like "special class name" somehow, but there is ReflectionNamedType::isBuiltin(), so "built-in type" might be preferable.
